Abstract (en)
[origin: WO2012134852A1] An optically clear composition includes a condensation curable silicone-organic copolymer. This copolymer has at least one alkoxysilane group, at least one T unit, and at least one Q unit. A silicon atom of at least one of the T and Q units is bonded to a urea group and/or a urethane group. This copolymer is condensation cured to form a film. In addition, a coating system includes a clear coat layer that includes the condensation cured copolymer and at least one sub-clear coat layer disposed in contact with the clear coat layer.
